What are destination tags?

Different tags for destinations:

destination - placename that the way exiting from the freeway leads to.

destination:ref - reference of the roads directly ahead.

destination:street - streetname the way exiting from the freeway leads to.

How to add destination tags?

Look out for red outer circle in Checkautopista for missing destination. Use Open in JOSM button to open the node in JOSM. Orange outer circle represents exit_to tag and we don't need to add destination tags in the way. Green outer circle represent that the concern way already has destination tag.

Download the data around the motorway_junction and mapillary layer to locate a signboard.

Use combination Mapillary images and Exit explorer to add destination as destination=* on motorway_link ways and the destination highway as destination:ref=*.
